Earlier in the month, HTC announced that it would release software updates to HTC One M9 and A9 in USA by December-end.
Keeping its promise, the company's regional head Mo Versi on Twitter, while wishing happy holidays to fans, confirmed that the Android M roll-out process will commence in a few hours time.
He said the HTC One (M8) will receive v6.0 Marshmallow, whereas the One A9 series will get the latest v6.0.1.
Some of the American One M9 owners have already begun receiving the update notification on their device. It is 1.21GB in size and brings Doze power-saving feature. If the device is in sleep mode, it will automatically put apps to sleep to increase the device's standby battery life. It can extend battery life by at least 30% depending on the device's internal hardware.
